TO ALL WHOM IT MAY CONCERN:

Be it known that I, WALTER J. BRnSSINGToN, of the city of Brooklyn, in the county of Kings, and State of New York, have invented a Gas-Burner, to be used as a perpetually-lighted burner or otherwise, and can be applied to any ordinary gas-bracket, burner, or chan'delier. p

The nature of my invention consists in producing a perpetual gas-burner, by placing a movable internal valve in the ordinary gas-burner, and operated so as to cut oil the force of the gas to the desiredquantity necessary to supply and give a small flame, for the purpose of producing a perpetual light, with little expense, and dispensing with the ordinary supply-cock or faucet.

To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation, in'whiehv Figure 1 represents a movable internal valve, A, with spiral spring B attached, and screw-hole c for screw D.

Figure 2 represents a top view of the movable internal valve A, showing the channels or grooves E E,'for the escape of gas, said grooves being cut bevclling, so as always to be kept clean by the constant pressure of gas, thus avoiding all future obstructions.

Figure 3 represents the packing F, made ofcork or other elastic material, with the plate G and screw D, for securing the same in its place.

Figure 4 represents the gas-burner H showing the internal valve-seat H, against which theinternal valve A, fig. I, is pressed in its operation, and the channels or grooves I I, for the escape of gas, and the oblong hole J,for the reception of the screw D, fig-3, and the notch'K, for holding the movable jacket M, fig. 6, in its position, when burning a full gas-light, and the female screw L, for attaching the same to any bracket, chandelier, or pipe, as X, fig. 4.

Figure 5 rcpresents a top view of the above figure, showing the outlets of the gas-channels I I.

Figure 6 representsthe movable jacket or casing M, with slot N, into which thecork packing F, plate G, and screw D, fig. 3, is allowed to traverse, showing also the pull 0, and the spring-point P, which is caused to slip in the notch K, fig. 4, when in the act of opening a full head of gas; also, the hood-band W, with the spring hood-holders Q Q, for securing the glass hood R, fig. 9, in its place in the hood-band W. Figure 7 represents another view of fig. 6, showing the position of the slot N, the pull O,.and the springpoint P, also the hood-band W.

Figure 8 represents a top view of the movahlojacket M, the position of the hood-band W and spring hoodholders'Q Q Q, the pull 0, and spring-point P.

Figure 9 represents the glass hood R, showing the flange S S, which, being pressed against the hood-holders Q Q Q, fig. 8, causes the glass hood Rite be firmly held in its position, at the same time being easily detached. Figure 10 r epresents my perpetual gas-burner complete, with full blaze T, by means of the pull 0 being b ought down so that thespring-point P is made to slipin the notch K, thus opening the internal valve A, fig. 1, and allowing a full head of gas t0 l)c exposed to the atmosphere.

/ Fi ure 11 re )reseuts. another view of m or etual as-burner com letewith a miniature li ht U h a I y p P a P a g 7 I y means of the pull 0 being raised, so that the spring-point P is released from the notch K, and brought up to V, thus closing the valve A, fig. 1, against the valve-seat II, fig. 4, and allowing the miniature night-light to be supplied with the smallest quantity of gas, escaping through the channels E F, figs. 1, 2.

' I Its Construction.

- I first construct a gas burneror shell, as represented at fig. 4, with an-internal valve-seat, H, through the top of which the channels I I are made for the escape of gas. At the lower end of this burner, at L, is made the female screw, of the usual size and form, for the purpose of; attaching the same to any ordinary bracket, chandelier, or pipe, as X.

On the outside, at K, I make a notch, for receiving the spring-point P, fig. 10, hereafter mentioned.

I next construct a valve, A, 1, to be one-half the length of the gas-burner H fig. 4, the top of which is turned perfectly true and concave, as seen at the dotted line E E A, fig. 1, and made to conform exactly to the internal convex valve-seat I H I, fig. 4. On the top of this valve A, fig. 1, a small groove or channel, E E, is made, for the escape of a small quantity of gas when the valve A is placed inside of the gas-burner H fig. 4, and against the valve-scat II. At the lower end of this valve A, fig. 1, I place a spiral spring, B, of sufiicient length, so that the valve A and spring 13, both together, shall be the same length as the gas-burner H", fig. 4, from H to L, said spring B being intended to act against the valve A, and press the same up against the valveseat H, fig. 4, when burning a faint night-light; hence, all the gas which will be burnt will pass through the small channels or grooves E E, fig. 2.

I next construct a movable jacket or casing, M, figs. 6, 7, the inside of which shall be of sufiieient size to closely fit over the gas-burner H fig. 4, but still sufficiently loose to slide up and down the same. In this jacket, on one side, I cut a long slot, N, fig. 7, of sufiicient width to receive the square washer or plate G, fig; 3, for purposes hereafter mentioned. On the lower end of this jacket M, I place a pull or handle, 0, figs. 6, 7, with a spring-point, P, placed in such a position that when the jacket M is brought down over the gas-burner H fig. 4, causing the valve A E E, fig. 1, to leave the valve-seat H, fig. 4, the'said spring-point I? will slip in the notch K, figs. 4, 10, thus holding all the movable pieces firmly in their places.

Again, on the upper end of the said jacket M, figs. 6, 7, the hood-band Wis firmly attached, and made of suificient size to admit of the glass hood R, fig. 9, being slipped inside, and firmly held in its place by means of the spring hood-holders, Q Q Q, fig. 8, said spring hood-holders being made from, and a part of, the hoodband V itself.

Having described each and every piece, I will now proceed to describe I Its Operation. 7

I first take thegas-burner II, fig. 4, and place over it the movable jacket M, fig. 6, after which I place the .valve A and spring B, fig. 1, inside of the gas-burner H fig. 4, in such a position that the screw-hole c in the valve A, fig. 1, shall be directly opposite the oblong hole J, fig. 4, for the purpose of inserting the screw D, cork packing I, and plate G, fig. 3, in their proper places, the cork packing preventing the escape of gas from the inside of the gas-burner, fig. 4, by coming in contact with the outside of the same, while the square plate G, fig. 3, is allowed to move and play freely in the slot N, in the side of the movable jacket M, fig. 7.

I next place the glass hood R, fig. 9, in position, by pressing the same inside of the spring hood-holders Q Q Q, fig. 8. This being accomplished, the whole assumes the appearance as represented at figs. 10, 11, complate for operation, and ready to be attached'to any bracket, chandelier, or pipe, as X, fig. 4.

In operating this gas-burner, it is' presumed that the position of the movable jacket M shall be up, as represented at fig. 11, with the spring-point I at -V. When in this position, thehction of the spiral spring 13 on the valve A,'fig. 1, is to press the valve A against the valve-seat II, fig. 4, which keeps the valve A constantly closed against said valve-seat H, fig. 4, and prevents the escape of gas through the burner at all times, thus obviating the necessity of a separate gas-cock or faucet, as at present used at its connection with a bracket or pipe. I

Again, by pressing down on the pull or handle 0, fig. 11, the movable jacket M slides down on the gasburner H until the spring-point P reaches the notch K, and the plate G'touchcs the under side of the hoodband W, as shown at D G, fig. 10, the valve A, fig. 1, still being closed, by the'action of the spiral spring 13 against the valve-seat H, fig. 4, while the spring-point P will not yet enter the notch K, as shown at fig. 10, it

being apparently tooshort: New, in order to open the valve A, fig. 1, and allow the spring-point If, fig. 10, to i 4 enter the notch K, an additional pressure is required upon the pull or handle 0, for the purpose of acting against the spira. spring B, on the valve A, fig. 1, which result is obtained by the pressure of the plate G, fig. 10, against the under side of the hood-band W, which again acts against the screw D,.thc latter being connected directly with the valve A at c, fig. 1, thus forcing the valve A from the valve-seat I-I, fig. 4, suilicient to allow a fullhead of gas to supply the-burner, also to allow the spring-point P (which was apparently too short) to enter the notch K, fig. 10, thus firmly holding the valve open.

1 Again, when the movable jacket M is raised, as represented at fig. 11, the action of the spiral spring 13, fig.

1, against the valve A, closes it against the valve-seat H, 4, thus preventing the escape of gas, except through the small grooves E E, fig. 2, which are just sufficicnt to supply a very small light, as shown at U, fig. 11. "The glass hood being above the light, effectually protects the same from any draught or'cu rrent of air, the transparent hood R allowing the light to be seen at all times during the night, offering facilities for finding the same, and instantly obtaining a full blaze, thus constituting a perpetual gas-burner.

Insumrning up my claims, I wish to say that I do not claim a self-lighting gas-burner, for that is already in use; neither do I claim a hood, for that'is already secured in combination with a self-lighting gas-burner; but

What I do claim as my invention, and desire to secure by Letters Patent of the United States, is-- I 1. lhc valve A, placed inside of the ordinary gas-burner, and operated so as to cut off the force of the gas to the desired quantity necessary to supply a miniature flame, substantially as described.

2. The valve-seat III I, formed by the under side of the tip in the ordinary gas-burner, against which the valve A seats itself, for the purposes specified.

3. The application of the spiral spring 15, in combination with the valve A, for the purposes herein specified.

4. The movable jacket M or casing, with the slot N, in combination with the band W, for the purpose of receiving the movable glass-protector or hood R, substantially as described. v

5. The combination of the internal movable valve A, with the elastic packing F and plate G and screw D, or their equivalents, substantially as shown and described, for the purposes set forth.

6. The application and use of the spring-point I, attached to the movable jacket M or casing, andthe notch K, to receive the same, for the purpose of securing the aforesaid movable jacket M or casing in its proper position, when it is raised to protect the small flame U, or drawn down to permit a full flame at T, as herein specified. p

7. A pull or handle, 0, or other suitable device, attached to the movable jacket M or casing, for the purpose of operating the seme eithe'r up or down, substantially as described and herein set forth.

AlLof which is respectfully submitted.
